SPINDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 353,409, dated November 30, 1886.

(No model.)

To all whom, it may concern:

Be it known that I, JOHN B. MoPHERsoN, of Lowell, county of Middlesex, and State of Massachusetts, have invented an Improvement in Spindle-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide means whereby a sleeve-whirl spindle may be retained in its bolster while the bobbin is being dotted.

My invention isV shown as embodied in well-known class of spindle-support, wherein a bolster is fitted loosely in a bolster-case attached to a rail, the pintle of the spindle entering the bolster, the sleeve-whirl surrounding the bolster-case. l

In accordance with my invention, the lower end of the sleeve-whirl is provided with an annular groove, which receives a lip forming part of a cap, the said lip being formed by cutting through the top of the cap eccentrically, thus forming a lip of variable width, so that in one position of the cap the collar or a suitable projection at the lower end of the sleevewhirl will enter the said opening, and thereafter the partial rotation of the'cap will place the lip in such position that the sleeve-whirl cannot be lifted or withdrawn from the cap. This cap has at its lower end a fiange, which is slotted to cooperate with cap-holding projections extending upwardly from the rail and being attached to some rigid part of the apparatus, the connection, as herein shown, be# ing with the bolster-case.l

Figure l illustrates an apparatus embodying my invention, the spindle being in elevation, all the other parts being in vertical section in the line w, Fig. 2. Fig. 2 is a side elevation of Fig. 1, the sleeve-whirl spindle being removed 5 and Fig. 3 is a plan or top view ot' Fig. 2.

The rail A, bolster-ease B, nut C, and bolster D placed loosely therein and constituting not only the lateral bearing but the step for the Vpintle a of the spindle a', having an attached sleeve-whirl, are and may be all as usual. The sleeve-whirl a2, as herein shown, is provided below the band-groove with an annular groove, g, to leave below it a projection, b.

. The supporting-case, or the annular curb c thereof, which constitutes the oil -well, receives about it a cap, d, the top of which (see Fig. 3) is cut out eccentrically, as shown at d', Fig. 3, leaving a lip, which varies in width. The cap d is provided with a projection, d2, slotted at one or more' points, as at 2. (See Fig. 2.) One or more projections, e, bent inwardly to form lips,'(see Figs. 2 and 3,) are eX- tended upwardly above the supporting-case. These projections e enter the grooves 2 and co-operate with the projection d2 of the cap to constitute a locking device therefor. The spindle being removed from the bolster, and it being desired to replace it, the operator will insert the grooved part b of the sleeve-whirlA into the eccentric hole d'in the cap d, and then place the cap upon the curb c, so that the slots 2 come opposite the projections e, and the cap d will then be turned until the lips d at the lower end of the cap pass under the projections e, the lips of the projection @riding above the projection ZZ of the cap, the eccentric hole d in the top of the cover, when applied to the curb, occupying a position out of center with relation to the projection b of the sleeve-whirl, a portion of the lip of the cap extending into the groove l about the projection b and preventing the lifting of the sleeve-whirl out of the cap.

Instead of the particular groove 2 and projection e, I may use any equivalent form of bayonet-locking device.

The cap is shown as provided with an opening, 3, and the curbc of the bolster-case with a hole, 4, through which may be introduced the point of an oil-can when it is desired to supply oil for the lubrication of the bolster and spindle, the cap having sufcient freedom of movement without disengaging it from the projection e to enable the hole 4 to be readily covered or IOO the cap d,for the said curb, the cap being provided with a hole, 3, at its side and with an opening in its top, which is covered by the sleeve-whirl, the holes 8 4 when in line serving for the admission of the nose of an oil-can, as set forth.

In testimony whereof Ihave signed my naine zo to this specification in the presence of two subscribing witnesses.

JOHN B. MCPHERSON.
